On Cloudultra 3 Women's Trail Running Shoes

Built for ultra-distance races on technical terrain. Featuring a CloudTec cushioning system for stability and efficiency, and Helion HF hyper foam for energy return and impact absorption, the Cloudultra 3 offers control over long distances.

Durable Leno Weave Upper

Featuring an engineered Leno weave upper, the Cloudultra 3 is durable and abrasion-resistant in zoned sections where durability is needed most, so you can take on rugged and mountainous technical trail terrains. This tough design keeps feet protected over trails, rocks and roots so you can continue your run with confidence knowing that you are covered. As well as this, the upper is breathable and quick-drying, working to keep your feet feeling cool, dry and comfortable during efforts. Allowing cool, fresh air to circulate, intolerable heat build-up can escape while moisture and sweat dry quickly to minimise distractions from discomfort. Completing the upper, a traditional lacing system locks down the midfoot to provide you with a secure fit that can be easily adjusted to suit you, preventing in-shoe slippage and ensuring a more stable ride.

Helion HF Hyperfoam Dual Midsole

Utilising cutting-edge technology, the midsole of the Cloudultra 3 delivers maximised energy return and ample cushioning thanks to a Helion HF hyperfoam. This smart tech allows you to power on through your longest trail runs, keeping your feet feeling fresher for longer, even after several hours on the trail. The Helion HF hyperfoam dual midsole ensures high energy return to push you forward with each and every step. CloudTec foam works alongside the Helion HF and ensures soft landings and smooth heel-to-toe transitions, delivering effortless feeling strides. Its refined domino-like construction propels you forward as each cell compresses. It has been combined with an engineered rocker to further maximise your running efficiency. Completing the midsole is a nylon Speedboard, which enhances stability and support, providing smooth transitions and underfoot protection.

Missiongrip Outsole

The outsole features an updated Missiongrip construction, complete with a new lug profile that has been developed with Finite Element Analysis (FEA). Performance-engineered and redesigned to be On's most advanced yet, this Missiongrip outsole offers unparalleled grip and traction for wherever your long-distance trail running takes you. The newly designed lug geometry keeps you in control on technical terrains.
